摘　　要：由于大庆油田M区块经过十几年的注水开发,又加上油藏发育具有非均质性,形成低效循环通道,开采难度日渐增大。针对上述问题需要设计一套适合该区块的深度调剖方案。结合文献以及现场提供的材料,选择适合本区块的深度调剖剂,在数值模拟的辅助下,通过物理模拟的方法,探究调剖剂的浓度、封堵率、调剖半径、调剖时机等因素对调剖效果的影响,为调剖工艺的优化提供数据参考,将相对成熟的调剖方案通过运用特定的数值模型进行方案预测,继而给出适合M油田最佳的调剖方案。The M block of Daqing oilfield has been developed by water flooding for more than ten years, and due to the reservoir heterogeneity, inefficient circulation channels have been formed, which increased the difficulty of exploitation. In view of above problems, a set of indepth profile control scheme suitable for the area need be designed. According to literatures and field materials, suitable indepth profile modificator for this block was screened out. The influence of profile modificator concentration, plugging rate, profile control radius, profile control timing on profile control effect was investigated by the method of physical simulation, which could provide reference data for the optimization of profile control process. The relatively mature profile control scheme for M block was evaluated by using numerical model, and then the best profile scheme was determined.
